The invention relates to envelopes and more particularly to an articleof this nature designed chiefly for containing offerings,

such as contributions to devotional institutions and for charitable andother purposes, whereby difierentcoins, or coin and paper money, may bekept separate by the donor,

'thereby facilitating the classifying of the donation and theaggregating or totalizing of the several offerings.

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

While the-drawings illustrate an embodiment of the invention, it is tobe understood that in adapting the same to meet different conditions andrequirements, various changes in the form, proportion and minor detailsof '30 construction may be resorted to without departing from thenature'of the invention.

Referring to the accompanying drawings forming a part of thespecification;

Figure 1 is a perspective iew of the en-' velope, the sealing flap beingextended,

Figure 2 is a View of the blank, and I Figure 3 is a detail view showingthe first step in the folding of the blank.

Corresponding and like parts are referred .0 to in the followingdescription and designated in the several views of the drawings by likereference characters.

The several parts are of uniformsize and constitute parts of a single blank, as indicated most clearlyin Figur 2. Securing flaps 4 and 5 are provided at adjacent edges of thefront 1 and corresponding flaps 6 and 7 are provided at adjacent edgesof the back 2. A sealing flap R is providedat the upper edge of thefront 1 and when closed extends over the partition 3 and back 2 and issecured to the outer side of the latter. By having the parts '1, 2 and 3of like extent, there is no liability of the contents of one pocketpassing therefrom into the other pocket. The blank is practically ofuniform width and is elongated as. 5 I

indicated most clearly in Figure 2.

\Vhen forming the envelope, the several parts are folded on the dottedlines indicated in Figure 2, which dotted lines assist ma-- initial stepthe blank is folded upon itself so that the partition 3 overlies thefront 1 terially in defining the several partsu In the after which thefiap 5 is folded upon the partition and adhesively secured thereto. Theback 2 is now folded upon the partition 1 3 and flap 5, afterwhich theflap 4- is folded upon the back 2 and secured thereto and the flaps 6and T folded'upon the front 1 and secured thereto.

The envelope is sealed by foldingthe flap 8 upon the back 2 and securing it thereto in the usual way. Itwill be understood that an envelope constructed in'accordance with thisinvention obviates the waste of material and insures separationofthe'contents of the two pockets and enables both pockets to be sealedby one and thesame flap.
